    Certain applications require that output voltage regulation be maintained when the input voltage is only slightly higher than the output voltage. For a buck converter, these low headroom operating conditions require high duty cycle operation that may approach 100%. As the converter on-time duration approaches the switching period, the charge on the BOOT capacitor must be maintained in order for th
